[Engine-devel] SSH Soft Fencing

Hi, SSH Soft Fencing is a new feature for 3.3 and it tries to restart VDSM using SSH connection on non responsive hosts prior to real fencing. More info can be found at http://www.ovirt.org/Automatic_Fencing#Automatic_Fencing_in_oVirt_3.3 In current SSH Soft Fencing implementation the restart VDSM using SSH command is part of standard fencing implementation in VdsNotRespondingTreatmentCommand. But this command is executed only if a host has a valid PM configuration. If host doesn't have a valid PM configuration, the execution of the command is disabled and host state is change to Non Responsive. So my question are: 1) Should SSH Soft Fencing be executed on hosts without valid PM configuration? 2) Should VDSM restart using SSH command be reimplemented as standalone command to be usable also in other parts of engine? If 1) is true, I think it will have to be done anyway. Martin Perina
